Abstract

A pneumatic radial tire has a pair of annular beads (2A, 2B), a tread (3) having a tread surface, a pair of side walls (4A, 4B) each interconnecting each of laterally opposite ends of the tread (3) and a radially outer end of each bead (2A, 2B), and a carcass layer (5) continuously extending through the inner sides of the beads (2A, 2B), the side walls (4A, 4B), and the tread (3) to form the framework of the tire. Main grooves continuously extending in the circumferential direction of the tread (3) are respectively arranged in both the tire's equatorial section including the center line of the tread (3) and the inner side of the tire, i.e., the side facing inwardly of the vehicle when the tire is mounted on the vehicle. Land block rows having blocks continuously arranged in the circumferential direction of the tire are located at positions away from the equatorial section of the tread (3) toward the outer side of the tire, i.e., the side facing outwardly of the vehicle when the tire is mounted on the vehicle. In a lateral cross section of the tire when the tire is filled with air, the curvature radius of the surface of a case line (5a) of the carcass layer (5) located on the outer side of the tire is greater than the curvature radius of the surface of a case line on the inner side.
